高含量铅的测定通常采用容量法。多金属矿石中的高含量铅,则要经过冗长的分离手续,最后以络合滴定法完成测定。原子吸收法(AAS)由于具有干扰少、简便、快速、准确等优点,已广泛应用于低含量元素的测定。近年来国内应用原子吸收法测定高含量无素的实用分析方法已有报导。 Determination of high lead content is usually the volume method. Polymetallic ore in the high content of lead, then go through a lengthy separation procedures, the final determination by complexometric titration method. Atomic absorption method (AAS) has been widely used in the determination of low content elements due to its advantages of less interference, simple, rapid and accurate. In recent years, the domestic application of atomic absorption spectrometry for the determination of high content of non-useful analytical methods have been reported.
